COMBINATION RUBBER. SIGNBOABD OB PANET; DETACHABLE LETTERS AND .IIGUBEB.Y

Application filed January 22, 1923. Serial No. 614,208.

bination Rubber Signboards or "Panels with Detachable Letters andFigures, of which the following is a specification.

My invention relates to sign boards and the like devices in combinationwith detachable letters and figures, and to the use of rubber asmaterial for such, and has for one of its objects to furnish a si nboard o panel with a rubber surface an articles representing letters andfigures adapted to be attached thereon without the use of any bindingsubstance. whatsoever.

Another object of the invention is to furnish a sign board or panel ofsuch a nature that articles representing letters, figures, etc. may beattached thereon and detached therefrom without leavin any marks orimpressions or otherwise dis re or injure the rubber surface of theboard or the letters or figures themselves.

A further object of the invention is to furnish a sign board or panelthat may consist of glass, covered with transparent rubber sheeting,thus roviding a device of this kind that may e illuminated in darkness bplacing a light behind it. A further o ject of the invention is toprovide means of constructing a sign-board and the like foradvertisement purposes or the like of a substance that can be washed andcleaned of dust, dirt, or other debris, so that its cohesive qualitywill not be aflected.

1 Furthermore, the object of this invention is to furnish devices andarticles of this nature adapted to be used in laces of business, publicinstitutions, etc, or advertising and announcement purposes-and,in-miniature sizes, to provide an educational, interesting, sanitary andunbreakable toy for children.

With these and other objects in view, the characteristic featuresand-scope of the invention will bereadily understood from the followingdescription taken in connection with the drawing forming a part thereofwherein: I

Fi 1 is a erspective view of the sign boar or pane with a pigeon-holedcabinetattached to the back thereof.

Figs. 2 and 3 illustrate the letters and figures and their construction.

Figure 4 isa detail cross-sectional view.

The board and panel, as represented by A in Fig. 1, is generally to beconstructed of wood, pasteboard or similar material and the frontsurface (or both surfaces) is covered with crude rubber sheeting or witha rubber compound or rubberized fabric, that have retained the cohesiveproperty natural to crude rubber, and may be of any suitable color.However, the board or panel may also consistof plate glass covered witha transparent rubber sheeting; when this is the case, a light may beplaced behind the board or panel at night, thus providing an illuminatedsign. The board or panel may have attached to the back part thereof acase or pigeon-holed cabinet as represented by C in Fig. 1, and whereinthe letters and figures may be stored when not in use. The cabinet maybe opened from the back part thereof, or, as shewn in Fig. 1 the boardmay be provided with hinges or hooks to permit it to be opened. Theboard or panel may also be suitably Igranlg'ed as shown in the drawingrepresented The letters and figures as represented by D in Fig. 1, andas illustrated in Figs. 2 and 3, have a base of crude rubber, or arubber com ound or rubberized fabric that have retained the co-adhesivequalit of raw rubber, and are mounted with vu canized rubber, metal,porcelain or an other suitable material, cemented or otherwise fastenedto the said base. E indicates a body .or base portion com osed of cruderubber. Reference numeral indicatesthe face of a letter which mayiconsist of vulcanized .i'ubber, metal, or other material which issecured to the outer portion of the casethrough the medium of anywell-known adhesive material. Or the letters and figures ma be madeentirely out of crude rubber, rub r compound or rubberized fabric.

The letters and figures are placed on to the rubber surface of the boardor panel by a slight pressure and retained in positron by means of thecohesive nature of the rubber. They are detached from the board by aslight ull. Attention is called to the fact that t e invention hereindescribed consists of providing a cover for a base which is inherentlycohesive or adhesive and in providing objects such as letters, figures,emblems, or the like and making them of the same or similar materialwhich is inherently cohesive or adhesive, whereby without the agency ofany additional adhesive material a sign, advertisement or the like, cafibe made on the base cover and changed to suit the particular business orline of advertisement desired at a particular time. In other words sothat the emblems, letters, pr figures or other objects, can be changedperiodically and without difficulty and without in any way marring,changing, manipulating, or affecting the base or cover in changing,removing, attachin or detaching the objects from the baseboard It alsoprovides means if desired, of facing the objects with different kinds ofmaterial such as porcelain, metal, glass or the like, by the use ofadditional adhesive material.

It further provides means of placing and arranging objects of differentcolors and different combination of colors, in different positions andmeans of reflecting different colors through a. base of transparentmaterial.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatWhat I claim is:

1. The combination of a base of suitable material, having a sheet ofcrude rubber attached thereto, which has retained its cohesiveness.objects having a base of crude rubber which are adapted to be mountedupon said crude rubber base and held thereto at any position by themutual cohesiveness of the crude rubber cover of the base the medium ofadditional adhesive material, as and for the purpose described.

2. Thecombination of a base composed of transparent material, onesurface of said transparent material being covered with a cohesiverubber compound, objects representing pre-determ-ined characters made ofcrude rubber material mounted on said base and being adapted to beafiixed thereto by mutual cohesiveness without the use of any adhesivematerial except the binding effect incident to crude rubber, saidobjects being also adapted to be detached therefrom each other Withoutshowing the effect of said attachment, as described and set forth,

3. The combination of a receptacle having a series of compartments forthe reception of different kinds of emblems, a member made of cruderubber attached thereto which has retained its adhesiveness, and objectsmade of crude rubber which have retained their cohesiveness mounted andsupported on said crude rubber member at predetermined locations by themutual cohesiveness only of the crude rubber member and said objects,and separate similar objects of different material adapted to beattached to the first named objects by the interposition of adhesivematerial, as described and set forth.

In testimony whereof, I aflix my signa ture.
